Okay! update for my tile already
I got thinking, there's like this clash all over the collab between wildlife and the aliens, and there's also some magma craters, and these green chemical craters around...So I kinda came up with this theory
The aliens come in to invade the collab, and they do it by pouring the green stuff on the land, which causes wild chemical reactions that produce the multi climate mess that's going around.....now, to oppose the aliens and their mischief, there's the orange (and green) reptiles who live underground, and come from the magma.....
it's a clash between nature and technology, summed up in the chemical reaction between two primordial soups =O
w00t it's primordial soup type symbology...=)

So my tile is going to have a magma crater below, with the green stuff dripping on it...making a snake emerge in righteous vendetta =O maybe I'll make an alien for her to chew around...IDK if I have enough room tho :p
